1 / 18 page SN54HCT245, SN74HCT245 OCTAL BUS TRANSCEIVERS WITH 3-STATE OUTPUTS SCLS020E – MARCH 1984 – REVISED AUGUST 2003 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 D Operating Voltage Range of 4.5 V to 5.5 V D High-Current 3-State Outputs Drive Bus Lines Directly or Up To 15 LSTTL Loads D Low Power Consumption, 80-µA Max ICC D Typical tpd = 14 ns D ±6-mA Output Drive at 5 V D Low Input Current of 1 µA Max D Inputs Are TTL-Voltage Compatible description/ordering information These octal bus transceivers are designed for asynchronous two-way communication between data buses. The control-function implementation minimizes external timing requirements. The ’HCT245 devices allow data transmission from the A bus to the B bus or from the B bus to the A bus, depending upon the logic level at the direction-control (DIR) input. The output-enable (OE) input can be used to disable the device so that the buses are effectively isolated.
